Processing and characterization of biobased polymer derived from Tacca leontopetaloides starch with rice husk silica and natural rubber blends / Nurul Shuhada Mohd Makhtar

The non-renewable source of petroleum based plastic such as Polyethylene (PE), calls for a need to look into this natural based polymer. Polylactic acid (PLA) is the promising synthetic polymer which is derived from the natural monomer lactic acid extracted from starch such as com starch; whereby ne...
